Transcript

I look down, and the Earth is down here. Oh, okay. Okay. Hurry, get back and do some more things. And I had another rest period. And so, this time, I took one foot out and did a little agility. And I looked. Oh, uh-oh. The Earth's not there. Oh, there it is, up there. To be in the space suit outside and to look out in any direction was pretty neat.... Read More

Questions & Answers

Q: What motivated the United States to launch its own space program?

The fear of losing the space race to the Soviet Union after they successfully launched Sputnik in 1957 drove the United States to develop its own space program for international prestige and national security.

Q: How did spacewalks save the Skylab mission?

In the Skylab mission, astronauts had to perform extravehicular activities to fix critical issues, such as deploying a solar array and a thermal canopy. Without these spacewalks, the Skylab mission would not have been successful.

Q: What are some challenges faced by astronauts during spacewalks?

Astronauts face difficulties such as limited time, fine motor skills requirements, extreme temperatures, and the potential risk of equipment malfunction. They must rely on extensive training and precision to complete their tasks successfully.

Q: How has spacewalk technology evolved over time?

Spacewalk technology has advanced significantly, from the first fabric-constructed suits to custom-made suits with integrated backpacks. Tools like power tools and water tanks for training have been developed to enhance astronauts' capabilities during spacewalks.
